The latest linux kernel doesn't boot on my computer
(h=21511abd0a248a3f225d3b611cfabb93124605a7).

elilo hangs while booting this kernel. 2.6.24 works.

Wow, so we know it's affected with EFI, since you're using elilo.

You gave absolutely zero other information about your system or what 
"doesn't boot" mean.

It's a macbook pro with a core duo processor (the one with only 32bits).


Doesn't boot means: i enter the name of the kernel image i want to boot in elilo
and press enter and nothing happens, it just hangs.

i need to press the power button for a few seconds to power off.

ELILO is expected to convert the memory map from EFI to e820 format.

EFI32 is likely to be poorly supported, since Apple is likely to be the 
only platform to *ever* ship EFI32 in mass production, and it has a BIOS 
emulation layer available.

I'm using elilo-3.6-ia32.efi provided at the elilo homepage.  i wasn't 
able to create a working efi toolchain :-(

I'm saying that in my opinion support for EFI32 is likely to be 
unreliable and never make it out of "experimental" status.  EFI is 
enough of a heap of junk on the 64-bit side.

Ying, do you have any insights?

3.6 doesn't do the mapping in ia32/system.c create_boot_params().
3.8 does.

The problem is, that i wasn't able to produce a working elilo.efi files 
with my gentoo toolchain. the files elilo-3.8.efi provided by the elilo 
project also doesn't work (gives a load error from the efi runtime).

So i guess i'm stuck here.

It should be noted somewhere that with Huangs patches, elilo version 3.8 
is needed.

The release notes with elilo3.7 beta (first integration of Intel EFI 2
patches) does cover this, as well as the toolchain changes required to
build it. fyi
